The gasket on my rear was leaking, so I decided yesturday to change it and the fluid. After dumping maybe a pint on the ground trying to fill it using various methods, I resorted to a hand operated siphon pump from Strauss. Squeeze bulb and the fluid flows. Simple enough. Also from my reading on here, there was always going to be some left in the bottom of the bottle.

Except it was slow. Took me an hour yesturday in the pouring rain to get a pint out of the bottle. Thinking there has to be a better way, I came upon this:

My father has a hose for his air compressor with a trigger operated nozzle on the end. Cut a small slit about half way down the bottle (obviously the bottle has to be less than half full), just long enough to snugly fit the nozzle. On the top, cut the tip enough to allow a hose to slip on about 1/4", requiring some force to get it on so it isn't loose. One quarter of an inch proved to be enough to hold the hose without you having to hold it. I prefer clear clear so I could see the fluid.

Slip the other end of the hose into the fill hole, and blow away. Be easy on the air pressure so you don't blow the hose off of the bottle cap.

Also, you must keep the air pressure low to avoid aerating the fluid. I ended up with a little at first, but not much. This is the benefit of the clear hose - you can see if its aerated, as well as being sure the fluid's moving.

Some tips:
- Watch the hose attached to the bottle cap. If it moves, you'll have to hold it yourself.
- Wrap a rag around the nozzle. Some oil will shoot out of the hole where it doesn't fit exactly.
- Hold the bottle upside down and point the nozzle toward the bottom of the bottle (the flat end). This helps reduce aeration.

When that half bottle's done, just refill and repeat until the fluid starts flowing from the fill hole.

Hope this proves useful. This method took less than 5 minutes for a full quart.

 

The easiest way, is to go to the marine store, and get a pump for outdrive lube. It fits the top of a quart gear lube bottle. Takes like 30 seconds to empty a bottle. Costs about $7.

 

Never heard of one before (not a mariner), so I wouldn't have thought of that. Kinda late now anyway.

 

Good Southern engineering--one thing that doesn't work: don't microwave your 90 wt. to loosen it up.

 

I never have a problem just squeezing the bottles

 

I should have mentioned, I had jack stands under the axle so there wasn't enough room to do that. I could squeeze it, yes, but probably couldn't even get half a bottle in that way.
